Named after three useful inhabitants on the other side, Betty, Boris and Boo are played in classic Red Tiger style on a 5x4 grid, using 30 fixed paylines. Thematically, this is not a dark game. The slot has been placed in a warm candlelit room, with only one clue to suspect it's haunted - the portraits of three ghosts hanging on the wall to the left. A curving staircase leads up to the next level on the right amidst cold blue light, but there isn't much that will raise the hairs on the back of your neck. Including scary spins when the ghosts finally show up.
